29月2022日、XNUMX年

根管治療とは何ですか?

If a tooth has pulpitis or apical periodontitis, the correct treatment is root canal therapy. Simply put, the purpose of root canal treatment is to try to remove the necrotic tissue, bacteria and their products in the root canal, and to form a certain taper, and to fill the root canal with sterile gutta-percha filling material, so as to achieve the purpose of three-dimensional filling and prevent the root canal. The re-invasion of bacteria promotes the recovery of the periapical tissue and restores the normal function of the teeth.

 

What are the steps of root canal treatment

1. Root canal preparation - open the tooth nerve cavity, completely remove the diseased tooth nerve tissue, measure the length of the root, and expand the root canal.

 

2. Root canal irrigation is a repeated operation in root canal treatment. The small fragments of organic matter in the root canal and the fine particles of hard tissue that have been cut off are rinsed with disinfectant.

 

3. Root canal disinfection - put special disinfection drugs in the root canal, and seal the hole with a temporary sealing material to further disinfect the root canal.

 

4. Root canal filling - use dental professional filling materials to seal the root canal tightly to prevent bacteria and other infectious substances from re-entering the root canal and causing new inflammation.

 

So after root canal treatment, what materials can we use for treatment?

1. PMMA : we can use Bloomden PMMA as filler material.

2. Porcelain crown: we can make crown for root canal treatment.

We are always choose porcelain crown and metal crown in our daily life, but Bloomden recommends choosing zirconia crowns, so what are the advantages of zirconia crown compared to metal crown?

 

Problems with metal porcelainクラウン:

1.金属とセラミックの接着に問題があり、脱落しやすい。     

2.金属には酸化の問題と酸腐食の問題があります。

口腔の酸塩基環境では、金属セラミックの歯はバクテリアの作用下で不安定であり、CTまたはMRI中に特定の金属干渉が発生します。

3.美的問題。

金属磁器の歯の縁は黒です。

これらのXNUMXつの問題について、ジルコニア磁器の歯の利点は次のとおりです。

1.ジルコニアクラウンには、金属とセラミックの接着の問題はありません。

2.ジルコニアは金属よりも安定しています。

3.Zirconia has good translucency and refraction, and will not appear black lines on the neck of the tooth, so that the neck of the tooth can also achieve a good aesthetic effect, which is impossible to catch up with metal porcelaincrown.
